Descripton
The full name of bearing steel is rolling bearing steel. It has high compressive strength and anti-fatigue performance, high hardness, high wear resistance and certain toughness, good hardenability, and extremely strict control of sulfur and phosphorus. It is a high-grade high-quality steel.
On the basis of GCr15 steel, the content of Si and Mn is
appropriately increased to improve its hardenability and elastic
limit, and its wear resistance is also better than that of GCr15.
The applicable size range for manufacturing rolling elements is
larger than that of GCr15.
High-carbon chromium bearing steel is widely used in the world, the
most commonly used types are GCr15 and GCr15SiMn, the performance
of the two kinds of steel is basically the same, but the quenching
permeability of GCr15SiMn is better than GCr15, so for larger size
bearing parts, should adopt GCr15SiMn steel, high-carbon chromium
bearing steel is widely used in the manufacture of rolling bearing
rings and rolling parts.
GCr15 bearing steel is widely used to manufacture spindle bearings,
railway bearings,engine bearings, machine tools bearings, mining
machinery bearings, general machinery bearings etc.
GCr15SiMn bearing steel is mainly used to manufacture thick wall
bearings, such as large and extra large size bearings, used in
heavy machinery and rolling mill machinery.
Chrome steel and other metal balls are processed by the following process:
Solid Chrome Steel Balls
Well-Made
Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.
High Hardness
Ball hardness is controlled within the HRC60-67 range as measured on parallel flat surfaces.
Wide Applications
The High Quality Chrome Steel Balls are mainly applied in Deep Groove Ball Bearing, Angular Contact Ball Bearings, Thrust Ball Bearings, Wheel Hub Bearings, Linear Bearings,wind turbine bearing, slewing ring bearing and also the Bearing.
